If you go down to that weight at your height, you ll be disgusting. Sorry. You would be grossly underweight and at risk for serious health problems (including death).
your extra weight is probably water weight, you could take a supplement that helps cut that water weight, but your not 18 so i cant really suggest a product.for the thigh stomach issue... do some cardio..run, jog, skip, whatever you feel
do you work out alot? if not, it would be good to just do crunches and leg lifts on a regular basis. squats are good to, that would be good to just get the legs and abs in shape. if you eat heavy, (which you probably dont) you should eat less. but it would be better to just work out more.
Firstly anywhere between 1400 -1800 cals of food is optimum2) EXERCISE, WORKOUT....NOTHING IN THE WORLD WILL MAGICALLY TRANSFORM U. 3) Have breakfast and never skip it within 1 hour of waking up. Have 5 meals a day instead of 3 to keep ur metabolism at its PEAK.HAve food high in protein medium in carbs and low in fat .supplement with green tea4) If u have been exercising its possible u r weight might increase or stay the same coz u might have gained muscle which is much heavier than fat5) Apart from cardio for around and hour - 1.5 hrs max do light weight training to tone urself and increase stamina.6) I wouldnt suggest to be in the gym more than 3 hrs a day unless u want to be in the olympics ..also rest atleast twice a week..7)FOOD- medium in carbs , high in fiber, low in fat , high in protein.Supplement with 2 cups of green tea.SEE THE DIFFERENCE....
